| Found in | Wikipedia, Oct. 15, 2012 (Ruthenium is a chemical element with symbol Ru and atomic number 44. It is a rare transition metal belonging to the platinum group of the periodic table.) WebElements website, Oct. 15, 2012 (Ruthenium Symbol: Ru. Atomic number: 44. Group in periodic table: 8; Group name: Precious metal or Platinum group metal; Period in periodic table: 5; Block in periodic table: d-block. Classification: Metallic. Ruthenium, rhodium, palladium, osmium, iridium, and platinum together make up a group of elements referred to as the platinum group metals. Ruthenium was isolated in 1844 by Karl Karlovich Klaus, who obtained ruthenium from the part of crude platinum that is insoluble in aqua regia. It is possible that a Polish chemist Jedrzej Sniadecki had in fact isolated ruthenium from some platinum ores rather earlier than this in 1807 but his work was not ratified, apparently as he withdrew his claims. He called it vestium.) |
